T0 all whom 'it may concern.'

Be it known that LABRAHAM Reoonsran, a citizen of the United States, -residing at Ladysmith, in the county of Rusk, State of Wisconsin, have invented certain' new and useful Improvements in Sleigh Knees; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains, to make and use the saine.V This invention relates to new and useful improvements in sled or sleigh parts and particularly to sleigh knees.

One object of the invention is to provide a sleigh knee which will permit the runner to rock in the proper manner, fore and aft,A

while preventing the forwardly and rearwardly slidingV thereof.

In the sleigh knees, as now made, there is provision for the forward and rearward rocking of the runncrs,but when going up hill the upper. portion ofthe knee, which is attached to thebox or body of the sleigh,

will slide Ybackwardly, while `upon going down hill, this portion will slide forwardly..

It is the particular Vobjectief the invention to provide a sleigh knee, formed of two' parts, but wherein the parts will not be permitted this objectionable sliding movement.

Other objects. and advantages will be apf parent fromthe following description when taken in connection with drawings.

In the drawings:

Figure 1 is a side elevation of a sleigh knee made in accordance with the'invention, and in connection with the runner and bumper.

Figure 2 is an end elevation of the knee, the runner being shown in cross section.

Figure 3 is an enlarged vertical transverse central' sectional view through the knee and runner, as well as the beam, on the line 37-3 of Fig. 1. Y

Figure 4 is ahorizontal longitudinal sectional view. on the line 4-'4 of Figure 1, above. the lugs of the lower sectionv of the knee.

the accompanying Figure 5 is a vertical transverse central .p

' ing drawings, A represents the lower. p0rtion of the knee, as a whole,said portion v comprising an elongated inverted channel specification of Lettersratent.

'seriaiNaav'ogz'ea 7 'I' member 10 which YVstraddlesthe uppe'r edge portionof vthe runner shoe 11, and issecured thereto "by the vertical: bolts y'12, passed through the ends of the portion 10and through the krunner shoe. .Formed on the upper face of the channel member 10, andV extending vertically therefrom, at points adjacent the ends thereof, are the posts 13, connected at their upper, ends by the longitudinally extending bar 14. It will be noted that the portions'of this connectingv bar 14, at theupper ends of the posts, are wider than the portion ,which exten-ds between the posts, thereby forming the shoulders 14,

are formed the anges 17, which are ar-V ranged to be secured to the lower face ofthe bumper or beam 18. In the opposite endsofthe bottom wall of thechannel memberVA 16 lare formed the recesses 19,.each of a size and shape to receive'one of the before-mentioned 'I i rugs 15. Y

The lengths yof the flangesy 17 are slightly less than the. distance between'the shoulders 14 at one` end of the bar l14, and

those -at'the other end, so that there willv be Vtion A. Y

The end portions of the beamV 18 are provided with series of openings 18' for thereceptionof the bolts 17', which secure the flanges 17 to the beam. n By this arrangement, the width of the sled may be varied according to the desires ofthe user, orthe charactergof the work to be performed. "1*

By reason of theY fact that the upper portion B is slightly rounded this permits rocking movement of this part with respect ,to the other, while the other portion A is Hat,

ping or sliding from one side to What is claimed is: A sleigh knee comprising a lower part and the other.

an upper part, the lower part Consisting of an inverted Channel having Vertical posts adjacent its ends, the lower portions of the posts having inwardly directed lugs, a eonneeting bar extending between the upper of the posts, and lianges on the upper ends of its sides disposed in the plane oi the connecting bar and? between the shoulders at one Y post and the shoulders at the other post, and

a removable bolt disposed through the side walls and beneath the oonneetingbar. l

In testimony whereof, I aflix my signature, in the presence of two witnesses.
